TowHoM I'T MAY ooNeEnn:

Be it known that I, PH. KNOBLOCK, 'of Wyandotte, in the county of Wyandotte, and State of Kansas, have invented a, new and valuable Improvement in Car-Couplers; and I do hereby declare that the following' is a full, clear, `and exact description of the construction and operation of the same, reference being had to the annexed drawings, making al part of this specification, and to the letters and figures of reference marked thereon.

Figures l and 2 are exterior views of my device, and

Figure. 3 is a. longitudinal section thereof.

The object of my invention is to provide better means than have heretofore been known or used for coup. ling and disconnecting railroad-cnrs, without obliging the operator to risk life or limb'by passing between such ears while the coupling and detaching process is'being carried on.

I call that portion of my device represented by the letters A. and B, respectively, the upper and lower jaws ofthe coupler, the jaw B being stationary, and the` `jaw A pivoted thereto at the point C, es shown. '.lhe letter D is a., slat, adjusted to the top of jaw B forithe purpose of holding the stop E in its place.

The stop E is fastened with a. screw, in .a mortise, under the lower side of slut D, in the manner represented. Its oliee is to serve'as a stop or spring, to prevent the A from beingopened more widely than is necessary, and to restore said jaw to its proper plnce after the object for which it was opened has been accomplished.

The letters G are.levers, pivoted to the sides'ofjawA in the manner shown.- The lower ends of these levers respectively rest upon the upper side of the jaw B at the point, and in the manner represented, and they nre united at their upper ends, above jaw A, by a cross-bar, H, in which I attach the cord by which the jaw A is drawn upward. It will be observed that, inasmuch as these levers G are pivoted to thc jaw A, the lower ends thereof are allowed to move forward upon the upper side of jaw B while the lifting process is being carried on, and to move backward thereon, while the'said jaw is being restored to its place.

The letter K is a swinging frame, composed of three' pieces, and forming three segments of aI square, with the top removed. This frameis slotted near the' upper ends ofthe side`pieecs thereof, and :t rod passes through said slots, and into the sides of jaw A, as shown at a. This frame is designed for lifting the coupling-hook, hereinafter mentioned. v I

The letter M is a coupling-hook, constructed in the form shown in fig. 3. Its immediate office is to form the connection between the-cars, and it is by releasing this hook from the jaws of the coupler that the cars nre detached.

The foregoing eomprises'a'suicient descriptiouot my invention, except that the-lower segment of frame K is united with a. platform or table, as shown at c, and the front ends of jaws A and B, respectively, a-re bevelled in\\nrds,as shown in iig. 3. This bevel-form is designed to furnish and serve as a guide for the coupling-hook when the same is being used for connecting the cars, and to allow space for the necessary oscil- 'lotions thereof, while the cars are in motion.

By means of the devices shown and described, the conductor or brakesman is enabled to disconnect the .ears by pulling a cord attached to the cross-bar II, and it will readily be perceived that the connecting-process may be carried on without passing from the platform.

What I claim as my invention, and desire to secure by Letters Patent, is

A earfconplor, havingjaws A and B, slotted frame K, cross-bor II, with cord attached as described, levers G, and hook M, constructed, combined, and arranged substantially as specified.
